Hiring can be complicated. Between finding the right talent and making sure all your legal bases are covered, there's a lot to manage.

 

One of the biggest challenges? Confirming that your new hires are legally authorized to work in the U.S.

 

That's where E-Verify comes in. It's one of the most effective ways to simplify your hiring process while keeping compliance airtight.

 

With immigration enforcement accelerating in 2026 and more regions adding mandates every legislative session, understanding E-Verify requirements by state is both smart business and essential.

 

If you've been wondering what E-Verify is, whether it's mandatory in your state, or how to stay compliant while building your workforce, here's everything you need to know.

 

What Is E-Verify?

 

E-Verify is a free, web-based system that compares information from your new hire's Form I-9 with records maintained by the U.S. Department of Homeland Security (DHS) and the Social Security Administration (SSA). Once your employee completes their Form I-9 (something all U.S. employers are required to do anyway), you enter that information into the E-Verify system and receive a case result within 3 to 5 seconds confirming whether the person is authorized to work.

 

Originally launched in 1997 as the Basic Pilot Program, E-Verify became mandatory for federal contractors in 2007 and has been expanding ever since. Today, over 1.3 million employers use the system and process more than 50 million verifications annually.

 

The system checks name and date of birth, Social Security number, citizenship or immigration status, and work authorization document details. What it doesn't check: criminal history, credit scores, or employment history. That distinction matters and it's where background checks come in.

 

E-Verify vs. Background Checks: What's the Difference?

 

When employers ask, “what is E-Verify compared to a background check?” these two tools are often confused, but they serve completely different purposes.

 

E-Verify answers one specific question: "Can this person legally work in the United States?"

 

Background checks answer a much broader question: "Is this person the right fit for our organization?"

 

Here's the practical breakdown:

  • E-Verify: Free. Completed after hire within 3 business days. Checks DHS and SSA records only. Cannot be used to pre-screen applicants since doing so violates the system's terms and can result in serious penalties.
  • Background Checks: Typically, $20–$200+. Run during the hiring process, usually after an offer is made. Covers criminal history, employment history, education credentials, and credit (if applicable).

 

Most employers need both. E-Verify handles the legal work authorization piece. Background checks provide comprehensive vetting that protects your business, your employees, and your customers. Neither replaces the other.

 

In fact, both tools, when used correctly, also contribute to increasing candidate interest. People want to work for employers who run a professional, consistent hiring process.

 

But here's where things get complicated. Is E-Verify mandatory? The answer is: it depends on where you are and what you do.

 

While E-Verify isn't required nationwide yet, it's mandatory for certain employers in specific situations. Let's break down the E-Verify requirements you need to know.

 

Federal E-Verify Requirements

 

E-Verify is required for all federal contractors and subcontractors whose contracts include the Federal Acquisition Regulation (FAR) E-Verify clause. This requirement has been in place since September 2009.

 

If you hold a federal contract worth $150,000 or more, you must:

  • Enroll in E-Verify within 30 days of contract award
  • Verify all new hires
  • In most cases, verify existing employees assigned to the federal contract

 

There are limited exemptions; however, employees with security clearances above the "Confidential" level don't need to be verified.

 

What States Require E-Verify? Location Matters More Than Ever

 

If you're asking what states require E-Verify, you're not alone. This is one of the most searched compliance questions and for good reason.

 

E-Verify requirements by state aren't always straightforward. Some apply mandates based on:

  • Employee count thresholds (like Florida's 25-employee minimum)
  • Employer type (public vs. private sector)
  • Industry (agriculture in some states has specific rules)
  • Contract value (for government contractors)

 

And here's a complication many employers miss: if you're hiring a remote worker in a state that requires E-Verify, you may need to use the system even if your company headquarters is in a state where it's voluntary. Always check the E-Verify requirements by state where your employee will be working.

 

E-Verify Requirements by State

 

Currently, 22 states have some form of E-Verify mandate. The requirements vary dramatically from state to state, which makes compliance challenging if you're hiring across multiple locations.

 

States requiring E-Verify for ALL private employers:

  • Alabama
  • Arizona
  • Mississippi
  • South Carolina

 

These four states have the strictest E-Verify requirements by state, mandating that virtually all employers use the system for every new hire.

 

States requiring E-Verify for certain employers:

State

Who Must Use E-Verify

Florida

Private employers with 25+ employees (as of July 2023)

Georgia

Public employers and private employers with 11+ employees

North Carolina

All state agencies and private employers with 25+ employees

Tennessee

All employers with 50+ employees

Louisiana

Public employers and contractors only

Utah

Colorado

Michigan

Department of Transportation contractors only

More states are considering E-Verify mandates every legislative session. Even if your state doesn't require it today, that could change within months.

 

Remember to keep in mind that E-Verify requirements by state vary significantly. Some apply to all employers, others only to public agencies or contractors above a certain contract value.

 

County and city ordinances can add another layer of complexity. Some municipalities require E-Verify for business license renewals, even if the state doesn't mandate it statewide.

 

How Long Does E-Verify Take?

 

Most E-Verify cases return results in 3 to 5 seconds. Cases that need additional review receive an "E-Verify Needs More Time" result and typically resolve within 24 hours, though some may take up to 3 federal government working days. Employers cannot take adverse action against employees during this period.

 

If the system returns a Tentative Nonconfirmation (TNC) (meaning the information entered doesn't match government records), you must notify the employee immediately. They cannot be suspended, have their training delayed, or face any adverse action while resolving the mismatch.

 

The employee has 10 federal working days to decide whether to contest, and 8 working days to contact DHS or SSA for resolution. Most TNCs are caused by data entry errors or name discrepancies, not actual authorization issues.

 

What's New: E-Verify+ in 2026

 

For employers still asking what E-Verify is and how it’s evolving, E-Verify+ launched in 2024 and is transforming how employers handle employment eligibility verification. It integrates Form I-9 completion and E-Verify into one seamless digital process.

 

After making a job offer, you initiate a case in the system, the employee completes their I-9 information electronically through a secure portal and uploads document photos. From there, E-Verify runs automatically.

 

The biggest advantage for today's workforce: E-Verify+ allows remote document examination without needing an authorized representative at the employee's location. It also includes built-in validations that catch common errors before submission, reducing violations significantly.

 

E-Verify+ is free, optional, and currently available to E-Verify employers with Employer Access accounts. It's rolling out more broadly throughout 2026. If you have remote employees or multiple hiring locations, it's worth exploring now.

 

Common E-Verify Mistakes to Avoid

 

Even well-intentioned employers get tripped up. Here are the most common errors and how to avoid them:

 

Pre-Screening Applicants

E-Verify can only be used after Form I-9 is complete, which only happens after someone is hired. Running checks before an offer is accepted violates the system's terms of use and can result in program termination and discrimination complaints.

 

Selective Verification

Once enrolled, you must verify every new hire. There are no exceptions based on appearance, accent, name, or perceived citizenship. Selective verification is a federal discrimination violation. Building equitable hiring practices starts with applying every process consistently.

 

Missing the Three-Day Deadline

E-Verify cases must be created within three business days of the employee's first day of work, not the date Form I-9 is signed. Each late case can be treated as a separate violation.

 

Taking Action During a TNC

Suspending an employee or delaying their start while a mismatch is resolved violates federal protections. Penalties include up to $16,000 per employee plus back pay and attorney fees.

 

Re-Running Existing Employees

 

E-Verify Is for New Hires Only

Running existing employees through the system without a legally required reason is a privacy violation and discrimination risk.

 

Not Training Staff

 

Every user must complete the required E-Verify tutorial before creating their first case. Untrained users are the leading source of avoidable violations.

 

E-Verify Penalties: What's at Stake?

 

The cost of getting E-Verify wrong is substantial. Current penalty ranges for 2025–2026 are the following:

 

  • Form I-9 violations: $272–$2,701 per form for first offenses, up to $21,916 for repeat violations. Every improperly completed form is a separate violation — companies with a large workforce can face six-figure fines quickly.
  • Knowingly hiring unauthorized workers: $676–$5,479 per employee for a first offense, scaling to $10,958–$21,916 per employee for third offenses.

 

Pattern or practice violations can result in criminal penalties including fines, up to six months imprisonment, asset seizure, and permanent debarment from federal contracts.

 

Failing to use E-Verify when state law or a federal contract requires it can additionally mean contract suspension, loss of business licenses, and state-level fines.

 

The cost of the E-Verify system itself is zero. The cost of ignoring it can be catastrophic.

What is E-Verify+?

E-Verify+ is an enhanced, free service launched in 2024 that combines Form I-9 completion and E-Verify verification into one digital process. It enables remote document examination, electronic document submission, and automated verification. It’s particularly useful for employers with remote or distributed workforces.

 

Can Employers E-Verify Remote Employees?

Yes, employers can use E-Verify for remote employees after completing Form I-9. For document examination, employers enrolled in E-Verify can use the E-Verify+ remote examination procedure. Employers not enrolled in E-Verify must use an authorized representative to physically inspect documents in the employee's location.
